Time to stop messing about. After spending far too long trying to 'do' insects with a simple generalist field guides and an internet search engine, I've finally bitten the bullet and added a bit of weight to the North Downs and beyond library. Pictured above is the answer to my ground beetle questions - a copy of 'The Carabidae of Britain and Ireland' by Martin Luff (with thanks to Josh for the tip off). I have also acquired the full set of John Walter's and Mark Telfer's visual guides to beetles, available here . Hopefully there will be more to come. Also arriving on the bookshelf was 'Lichens' by Frank Dobson and 'Wasps of Surrey' by David Baldock. I ordered all of the three books mentioned in this post from Subbuteo Books and all three arrived within 48 hours - excellent service. Now, where can I find a ground beetle....
